Of the twelve species of the genus Atomaria known from Madeira and/or the Canary Islands, six are endemics, and are apterous. They have no doubt evolved in situ. The eight species (excluding a replacement name) described by Wollaston are represented in the British Museum, one (pilosula) by the holotype, the remainder by lectotypes designated by the writer. Five of Wollaston's names are valid. A timetable of facts relating to Wollaston's researches and collections is presented.
